Visualizing Crashes

This interactive map shows the point locations of reported vehicle crashes that occurred in 2021 from the VDOT dataset available here. You can zoom, pan, and click on features to reveal selected attributes in a popup window.


The kernel density layers shown here are estimates of the intensity of the underlying, unobserved process that produces an observed point pattern (i.e., the mapped location of reported vehicle accidents). It is useful for identifying areas where crashes are expected to occur more frequently.


The Influence of Weather

Weather conditions are sometimes a factor in vehicle accidents. However, about 87% of the crashes in the VDOT dataset (1404 of 1614) were not determined to be weather-affected. Rain was the most commonly cited factor in weather-affected crashes (173 of 1614).



The interactive map below is similar to the one shown above, but it only displays crashes from the VDOT dataset that were determined to have been weather-affected.
